At some point over the last couple of weeks, you'd expect that Alan Browne and Kevin Long had to warm up their vocal chords and step in front of their new teammates.
The trio were some of the new players added to Martin O'Neill's group for the games against Mexico, Uruguay and Sunday's World Cup qualifier against Austria.
As newcomers, they would have had to perform in front of their more experienced teammates.
Speaking on Jarlath Regan's 'An Irishman Abroad' podcast, which was recorded prior to his injury in March, Ireland captain Seamus Coleman said that following Robbie Keane's departure as captain, he has taken over as the one who taps players on the shoulder and tells them it's their turn to serenade the group.
It's been passed onto me. Obviously the first few trips, I let John O'Shea do it because although I've got the armband, he's a player that I massively look up to and massively respect.
John did it for the first few but made sure I stepped up. So, I've been doing it recently.
It's nearly seven years since Coleman received his first Ireland call-up. When his turn to sing came, he chose the theme tune to The Fresh Prince Of Bel-Air.
Of all those he's heard perform down the years, Shane Duffy stands out as the most memorable. The Derryman sang 'Build Me Up Buttercup'.
There's been mix of stuff really. There's been that many through the years that you don't remember.
Shane Duffy sang 'Buttercup'. That was terrible, so I remember that.
The tradition is not meant to embarrass new caps. Rather, it serves as a way to integrate them into the group.
I think we've all been quite terrible to be honest. We'll stick to the football, I think.
It's more nerves than anything else. It can be after dinner until it gets out of the way.
It's great. It brings lads who are coming in for the first time into the group. It gives them something to chat about.
